Windows and Energy Efficiency: How to Keep Your Home Comfortable Year-Round
In ancient times, windows were little more than holes in walls used to let in light and air. Style and efficiency were not considerations. Today, windows are both functional and aesthetic, combining technology and design to improve energy efficiency and reduce heating and cooling costs.
Modern windows allow sunlight to warm your home during winter, prevent heat loss, and keep cool air in during summer—all while enhancing your home’s appearance.
Should You Repair or Replace Your Windows?
When evaluating your windows, consider their age and condition. Poorly constructed or outdated windows can lead to significant energy loss.
Increasing Efficiency Without Replacement
If your home is over 30 years old and still has original windows, chances are they are not performing as efficiently as modern alternatives. However, there are cost-effective ways to improve their efficiency:
-
Weatherstripping: Tighten seals around windows to prevent drafts. Caulking cord, available in rolls, is easy to install and works on wood, metal, aluminum, and vinyl frames.
-
Storm Windows: Ensure existing storm windows are in good condition and properly installed before winter. They reduce heat loss and protect against icy winds.
-
Plastic Sheeting: If you lack storm windows or they are damaged, heavy-gauge clear plastic sheeting can be an inexpensive, effective alternative. Seal it tightly over your existing windows to improve insulation.
When to Consider Replacing Windows
Replacing windows doesn’t have to be done all at once. Start with the ones causing the most heat loss—typically large picture windows in living or dining rooms. Staged replacements spread out costs while still improving energy efficiency.
Types of Windows to Consider:
-
Double-hung
-
Casement
-
Stationary
-
Awning
-
Horizontal sliding
Materials include wood, aluminum, vinyl, or combinations of these. Look for windows with insulated glass, tight seals, and easy-to-clean designs to eliminate drafts and improve comfort.
Choosing the Right Windows
Before making a purchase:
-
Visit multiple suppliers to compare products and options.
-
Consider both aesthetics and functionality—windows should enhance your home’s appearance and improve energy efficiency.
-
Decide whether you’ll install them yourself or hire a professional for a precise, efficient installation.
By selecting the right windows, you can increase comfort, reduce energy costs, and boost the value of your home—all while improving its curb appeal.
